Price targeting can help the poor in some cases and hurt them in others. For essentials where the need to purchase is high and the provider has a semi-monopoly, dynamic pricing leaves everyone worse off. For instance, think of groceries where there is only one store nearby or medicines with only one producer.

On the other hand, for something like a Netflix subscription, price discrimination DOES tend to help the poor users out. Netflix is 10x cheaper in third world countries for the exact same product. If they were forced to charge the same price everywhere, they would just charge everyone the US price and foreign users would be left out.

Per customer pricing will squeeze every customer for every dollar they can possibly afford. The more data they have the more they can calculate the level of desperation for each purchase. If they have your message history and see your mum is dying, they can spike flight tickets for example. And they will know exactly the highest amount you can afford for it.

Price discrimination at all is not the same as individualized prices. And really the issue conflates two things: 1, privacy and surveillance pricing; 2, AI profit-maximizing.

Even if Netflix or others do price-discrimination, the AI-pricing issue would still be used to squeeze as much as possible from the poor. It's not like these blood-sucking capitalists who run these massive corporations are into helping the poor.
